Activerecord Settings

This gem creates a very simple activerecord based key value store. It can be useful if you want a place to store stuff that is more durable than a redis/memcache cache, or you simply don't want or need the complexity of running an additional cache.

Add this line to your application's Gemfile:

gem 'activerecord_settings'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activerecord_settings

Create the migration to create the activerecord table with

bundle exec rails g activerecord_settings:install

Then you can set and get values like this

ActiverecordSettings::Setting.set('key', anything_yaml_can_serialize)
ActiverecordSettings::Setting.get('key')
=> anything_yaml_can_serialize

You can also set keys to have expiries

ActiverecordSettings::Setting.set('key', "It's morning", expires: 10.minutes.from_now)
ActiverecordSettings::Setting.get('key')
=> "It's morning"
# Some time passes, Thorin sings about gold
ActiverecordSettings::Setting.get('key')
=> nil

ActiverecordSettings::Setting is a bit of a mouthful, so you can create a shorthand for it by putting something like the following in an initiliazer

Setting = ActiverecordSettings::Setting

And then you can do this

Setting.set('key', anything_yaml_can_serialize)
Setting.get('key')
=> anything_yaml_can_serialize
